I like to think of spaghetti squash as nature’s original pasta. With its soft angel hair texture, spaghetti squash is a delicious ingredient that you can swap in for any traditional pasta recipe.

Registered Dietitian Brenda Duby, RD says, “Spaghetti squash is a winter squash that is gaining popularity as a lower calorie, lower carb alternative to pasta.”  She notes some of the nutritional benefits of this vegetable, including beta-carotene, and vitamins C, K, and B vitamins.

And with this list of 30 Keto Spaghetti Squash recipes, you’ll find everything from inventive twists on classic lasagna to new “noodle” casseroles, all using Keto-friendly spaghetti squash.

And spaghetti squash has way more to offer beyond pasta recipes. The natural shape of the squash makes it perfect to stuff with delicious fillings! Our spaghetti squash recipe list includes everything from chili cheese squash boats to pork and egg breakfast cups!

Keto Spaghetti Squash Pasta Recipes

30 Simple But Sensational Keto Spaghetti Squash Recipes

Ingredients: spaghetti squash, ground or minced beef, onion, diced tomato, fresh basil, garlic, coconut oil, salt, pepper.

Using spaghetti squash is a healthy alternative to traditional pasta and can be eaten just the same way. This recipe is a perfect way to introduce squash into your children’s diet and they could even learn to love it as much as they love pasta. If you add in the basil at the end of the cooking time it helps to retain the full freshness of the flavor.

Ingredients: raw bacon, butter, sugar snap peas, cherry tomatoes, scallions, lemon zest, parsley, cooked spaghetti squash, grated parmesan cheese, salt, pepper.

I am a great believer in food looking a good as it tastes, and this dish is the perfect example! It is bright and colorful because of the tomatoes and sugar snap peas and has loads of flavor from the bacon and parmesan. I can imagine that this dish would be great for a summertime lunch, or to make it a bit more substantial you can add in other vegetables like broccoli and mushrooms.

Ingredients: chicken breasts, spaghetti squash, cajun seasoning, cayenne pepper, heavy cream, butter, black pepper, garlic salt.


There is something really great about pairing spiced meat with a creamy side – they just seem to work together! Here you have Cajun-spiced chicken served with spaghetti squash in a thick and creamy sauce that gives you a dish that is wholesome, satisfying and so delicious! When I cook this keto spaghetti squash recipe I also like to wrap the chicken breast in bacon after seasoning, and that gives you more flavor and extra protein.

Low-Carb Spaghetti Squash Lasagna (Contains Dairy)

– Wicked Stuffed

Ingredients: spaghetti squash, ground beef, Parmesan cheese, chili powder, oregano, basil, garlic, sea salt, pepper, egg, pasta sauce (Rozzano Marinara Sauce), red pepper flakes, mozzarella cheese.

My family went mad over this recipe, not because it was low carb, but because they had never had a meatball lasagna! This is a great idea as it adds to the texture and is a great way to encourage the kids to eat healthily. The spaghetti squash does not taste the same as pasta but makes a fantastic alternative when eating low-carb. This dish looks authentic if you top it with the cheese, but the choice is yours!

Low Carb Spaghetti Squash Alla Carbonara (Contains Dairy)

– Sugar-Free Mom

Ingredients: spaghetti squash, bacon, garlic, Parmesan, eggs, heavy cream, fresh basil, fresh parsley, lemon zest, salt, pepper.

Because you are using dairy in this recipe, the finished product really has the authentic carbonara flavor, so if you tolerate it, give this a go! There are loads of flavors in this, from the salty bacon, the parmesan, and the added herbs, and the whole dish is so tasty it is bound to become a family favorite. When cooking the sauce, try to cook for long enough to thicken it so it will stick to the squash.

Autoimmune Paleo Pesto Chicken and Spaghetti Squash

Ingredients: spaghetti squash, boneless skinless chicken breast or thighs, coconut oil (or other cooking fat), basil, arugula, olive oil, lemon juice, garlic, sea salt.

The pesto used in this recipe is totally nut-free, making this a lovely family meal to serve if there is anyone with nut allergies. The pesto is the star of the meal with all the flavors of the herbs and the aromatics from the fresh basil and garlic. Serve this over chicken thighs for a budget-friendly meal, or use chicken breast if you would rather. If you don’t like arugula, spinach makes a great alternative.

Ingredients: spaghetti squash, olive oil, Italian seasoning, garlic powder, sea salt, water, nutritional yeast (optional).

This is a basic recipe explaining how to cook spaghetti squash and season it with either Italian seasoning or fresh herbs if you have them. This could then be served as a side with a meat sauce such as a Bolognese sauce or with grilled meats. If you like your ‘pasta’ cheesy you can add in some nutritional yeast, or if you tolerate dairy you can top with shavings of parmesan.

This recipe is quite a basic one which you can use as a guide to making your own meat sauce. For example, you could add in onions, mushrooms, and garlic for a completely new dish. Also, you can experiment with different seasonings, or add in some fresh herbs to make it your own design. Even as it is this is a filling and very satisfying meal!

Keto Spaghetti Squash Casseroles & Bakes Recipes

This lovely keto squash casserole makes a delicious side for loads of different meals and can be flavored up to suit your main. For example, if you are serving an Italian dish you can add in some basil and Italian seasoning, or for Asian-inspired dishes, you can use garlic, ginger, and cumin. You can also add extra vegetables like mushrooms and green beans to make this a vegetable-based main course.

Ingredients: Mexican chorizo, cooked spaghetti squash, cheddar cheese, salsa verde, eggs, cilantro (optional).

If you are looking for keto comfort food then look no further! This recipe gives you an individual nest of spaghetti squash, packed with the flavor of the chorizo, cheese and salsa verde, and topped with an egg, so when you cut into it the yolk runs over the top. This dish is hearty, filling and so delicious and would make a great tasty meal at any time. To spice things up you can use a stronger chorizo.

Ingredients: spaghetti squash, butter, coconut flour, chicken stock or broth, coconut milk, salt, pepper, boneless & skinless chicken thighs, frozen broccoli or vegetable of choice, Parmesan cheese, crushed pork rinds (optional), cheddar cheese.

It is important when making dishes with broth that you use homemade if possible as it is more natural and has no additives but is full of flavor. So next time you have roast chicken, simply boil up the bones and save the broth for dishes like this. This casserole recipe is super-tasty with its cheesy, creamy sauce and chunks of chicken, but you could add in different vegetables or even try using sausage instead of chicken.

Ingredients: spaghetti squash, olive oil, butter, garlic, onion, salt, pepper, bacon, sour cream, sharp cheddar cheese, Parmesan cheese.

There is something really wonderful about cheese and bacon in a dish that makes me think of the comfort food of my childhood, and even my daughter thinks that cheese makes everything better! This casserole is so tasty and can be easily reheated, so leftovers never go to waste. I sometimes serve this on its own, but it also makes a great recipe for a side dish with steak or grilled chicken.

Ingredients: spaghetti squash, favorite pasta sauce, ricotta cheese, cheddar cheese.

This is a basic recipe that allows you to use whatever pasta sauce you prefer, so you can turn this into a family favorite. This dish is based on a popular Italian meal but feel free to experiment by adding meat or other vegetables. I often chop some pre-cooked chicken and add that along with some mushrooms for a hearty and filling keto dinner.

Low Carb Baked Spaghetti Squash Casserole Recipe (Contains Dairy)

– Grass Fed Girl

Ingredients: spaghetti squash, spaghetti sauce, dried oregano, ground beef, eggs, sea salt, ground black pepper, fresh basil, grated Parmesan (optional).

When you cook spaghetti squash to make a casserole, you will notice that it gives off quite a lot of liquid, so when you are scooping out the strands, let them sit on a clean towel for a few minutes then you won’t get a watery casserole. Because I am a huge garlic fan I like to add a minced garlic clove to this recipe to make it even yummier, but it is up to you!

Spaghetti Squash Breakfast Cups

– My Heart Beets

Ingredients: ground pork, salt, spaghetti squash, eggs.

I just love the idea of individual breakfast cups, because they can help with portion control and stop me over-eating! These are so tasty and easy to make and they freeze well too, so I tend to batch-cook these for breakfast through the week. For a slightly different flavor, you could use chopped breakfast sausage of your choice instead of ground pork in this recipe.

Spaghetti Squash Casserole

Ingredients: spaghetti squash, avocado oil, red onion, serrano pepper, garlic, ground beef, oregano, paprika, cumin powder, fresh thyme, turmeric powder, chili powder, red pepper flakes, salt, pepper, green bell pepper, tomatoes, egg, green onion.

When I first saw this keto spaghetti squash recipe I was quite surprised by the number of spices used, but then spaghetti squash does not have a strong taste and can carry the spices really well. The Indian spices give this dish a wonderful flavor and it is warming, filling and totally satisfying. I often make dishes like these on colder nights, when you need some spice to warm you after a busy day.

Spaghetti Squash Crusted Quiche

– PaleOMG

Ingredients: spaghetti squash, pork breakfast sausage, eggs, dried parsley, dried basil, salt, pepper, mushrooms (shiitake), coconut oil.

I had never tried using spaghetti squash as a crust before I tried this recipe, but now I make them like this all the time! Even when I am not strict about eating low carb, I find this way better as the crust is not so heavy. This quiche tastes so good cold as well, so would make a lovely portable lunch to take to work. If you tolerate dairy, you can top the quiche with grated cheese, but it is tasty enough without it.

Keto Spaghetti Squash Boats Recipes

Chili Cheese Stuffed Spaghetti Squash (Contains Dairy)

– Low Carb Yum

Ingredients: spaghetti squash, ground beef, dried onion flakes, minced garlic, diced tomatoes, chili powder, salt, paprika, oregano, cumin, dried red pepper (optional), shredded cheese.

Now, this is my idea of comfort food that would be great on a cold day as it is spicy, meaty and satisfying! This recipe gives you six generous servings, and I found it fed my family of four with enough left over for lunch the next day. If you don’t like things too spicy you can easily cut down the amount of chili powder you use, but spaghetti squash can take the heat down a bit so taste it first before adjusting the amount.

Nightshade-Free Taco Beef Spaghetti Squash Boats

Ingredients: spaghetti squash, water, olive oil, green onions, yellow onion, ground beef, cumin, onion powder, dried oregano flakes, sea salt, garlic powder, ground turmeric, ground cinnamon, fish sauce, mayo or coconut cream, cilantro, black olives, nutritional yeast, avocado cream.

I really like the idea of serving foods in shells or ‘boats’ as they can make a simple meal look amazing on the dinner table. This recipe gives you a heart-warming meal with all the flavors of the spices and the beef, topped off with the smooth and delicious avocado cream and green onions. This would be a great main for a Mexican-inspired dinner party with friends.

Ingredients: spaghetti squash, ground beef, onion, garlic, tomatoes, chopped vegetables (kale and mini sweet peppers), jalapeno, taco seasoning, kosher or sea salt, lard, (Optional: nutritional yeast, guacamole, pico de gallo.

Not only does spaghetti squash make a great low carb alternative to pasta, it is reasonably priced and can be used to make some dishes go a bit further if you are catering on a budget or have a large family to feed. This may not be the prettiest dish you’ve seen, but the flavor is amazing and it tastes so good served with homemade guacamole and pico de gallo or a salsa of your choice.

– Savory Lotus

Ingredients: spaghetti squash, coconut oil or ghee, fresh basil, olive oil, lemon juice, garlic, sea salt, hemp seeds or raw pumpkin seeds, bacon.

This spaghetti squash dish has all the flavors of the Mediterranean thanks to the olive oil, garlic, and aromatic basil. This is great, but made even better because it has bacon! You will find the strands of squash take on the green color of the pesto once they are combined, and I find that kids love it because of this. I found that you don’t really need the lemon juice, but you can decide when you taste it.

Spaghetti Squash Lasagna (Contains Dairy)

– Kasey Trenum

Ingredients: ground beef, spaghetti sauce, spaghetti squash, ricotta cheese, Parmesan cheese, mozzarella cheese, egg, Italian seasoning, garlic.

Here is another delicious keto recipe served in a spaghetti squash boat that would grace any dinner table. You have the traditional flavors of a lasagna dish but without the pasta which can increase inflammation. I love the ricotta cheese layer at the bottom which adds a creamy texture, then you have the meat in the middle and more cheese on top. This is comfort food at its best!

Other Keto Spaghetti Squash Recipes

Ingredients: spaghetti squash, olive oil, water, Spinach Artichoke and Bacon Dip, light coconut milk (optional), mushrooms (optional), artichoke hearts (optional), salt, pepper, garlic powder, oregano.

One of the best things about spaghetti squash is that it takes on the flavors of the other ingredients, so you can use it in a variety of dishes. This recipe uses artichoke and spinach which are quite grown-up flavors, so this would be great for a dinner party, especially if you add the extra artichoke hearts. If you don’t want to use mushrooms in this recipe you can use a different vegetable like broccoli.

Bacon Quiche with Spaghetti Squash Crust

Ingredients: spaghetti squash, coconut oil, bacon, red bell pepper, leek, eggs, full-fat canned coconut milk, salt, black pepper, basil.

The first thing that hits you when you make this amazing quiche is the rainbow of colors from the bell pepper and leek. The flavors come out really well and you have the added delight of bacon pieces through the quiche. Try to press the squash into the sides of the dish before filling so it will hold its shape better. This quiche does not freeze well, so store it in the refrigerator if there is any left!

Ingredients: spaghetti squash, eggs, ground beef, taco seasoning mix, tomato sauce, water, grated cheese, tomato, avocado, sour cream (optional).

Like traditional tacos, these little nests can be served with a range of toppings such as guacamole, chopped onions, and tomato salsa, so this dish could be made for a low carb Mexican-themed meal for the family. I like to serve these with toppings in separate bowls so the family can help themselves to the toppings of their choice. A really fun family lunch for the weekend!

Ingredients: eggs, spaghetti squash, Italian Salsa (or tomatoes, basil, and shallots), goat cheese (optional), extra virgin olive oil, salt, pepper, garlic powder.

This keto squash recipe is great for using up leftover spaghetti squash strands from a casserole as you are only using it to form the base and it gives you a lovely filling and tasty frittata for breakfast. If you don’t have Italian salsa you can simply use basil, tomatoes and shallots or chives, so this is a totally adaptable recipe. If you need more protein, you could even cook up some ground beef and add that in too.

Creamy Teriyaki Spaghetti Squash Salad

Ingredients: spaghetti squash, Polish Kielbasa from Coleman Natural, coconut oil, cilantro, green onion, red cabbage, homemade mayo, Coconut Secret Teriyaki Sauce, lime juice, sea salt.

If you have never tried spaghetti squash cold, just think ‘pasta salad’ and you will realize that it works! It takes on the flavors of the seasonings and the flavor gets more intense if you can leave it overnight. This keto spaghetti squash recipe is a fusion of crisp vegetables, creamy sauce, and meaty sausage all mixed with lime and the seasonings that give you a satisfying dish for breakfast or lunch.

Spaghetti Squash With Cilantro-Macadamia Pesto

– Rubies and Radishes

Ingredients: spaghetti squash, chicken, fennel bulb (optional), cherry tomatoes, fresh basil, ghee, cilantro, garlic, green onion, paprika, macadamia nuts, olive oil, lemon zest, lemon juice, salt, pepper.

Sometimes a dish of ‘pasta’ and chicken can look and taste a bit bland and uninspiring, but when you mix in some homemade pesto it brings the whole dish to life, just like here! This pesto has the wonderful mix of flavors of garlic, basil, and lemon – a true taste of the Mediterranean – which can turn this keto meal into a show-stopper as the squash takes on the color of the pesto too!

Low-Carb Spaghetti Squash Breakfast Nests (Contains Dairy)

– Keto Diet Blog

Ingredients: spaghetti squash, eggs, marinara sauce, ghee, duck fat or lard, salt, pepper, (Optional: bacon slices, cheese, avocado, fresh basil, etc.).

Breakfast used to be boring in our house until I discovered that serving eggs in nests was so much more exciting! These would be perfect for Easter Sunday breakfast, or any Sunday come to think of it. I am not a fan of marinara sauce, so I serve these with crispy bacon strips and snipped chives for garnish, but you could serve with any other toppings you prefer.

Spaghetti Squash with Garlic and Parsley (Contains Dairy)

– Low Carb Maven

Ingredients: spaghetti squash, butter, garlic, parsley, Parmesan cheese, salt, pepper.

This recipe is designed to give you a wonderfully tasty side that you can serve with loads of different proteins, but I think it goes really well with Italian-based dishes or simple ones like grilled chicken breasts or pork chops. The garlic and parsley give the squash a wonderful flavor and this is made even better if you decide to add in the parmesan cheese!
